Data bus Systems 2003 and newer GM Trucks/SUV’s, ‘96-04 Jeep Grand Cherokee
Data bus systems send low current “Data messages” to the door lock controllers on a network in order to
lock and unlock the vehicle. To install aftermarket systems in these vehicles, an interface module is required
that converts the regular lock/unlock pulses into “Data messages” to allow locking & unlocking. This type
system requires that you have a good working knowledge of their operation before attempting installation of
alarm functions. “Engine Start” only function can be easily installed.
